Abstract

L'invention concerne un procédé de notification de libération du contexte de terminal, un dispositif réseau et un support de stockage informatique. Le procédé comprend les étapes suivantes : lorsqu'un terminal convertit d'être connecté à un second nœud de réseau pour être connecté à un premier nœud de réseau, ou, lorsque le terminal convertit d'être connecté à un second système de communication pour être connecté à un premier système de communication, le premier nœud de réseau transmet une première notification au second nœud de réseau ou au second système de communication, la première notification étant au moins utilisée pour notifier au second système de communication ou au second nœud de réseau de libérer un contexte du terminal ; et lorsque le terminal est connecté au second système de communication ou connecté au second nœud de réseau, le second système de communication ou le second nœud de réseau sauvegarde le contexte du terminal.
